Single Folding Gate Installation Instructions

• 1. Determining Gate Placement: Determining gate placement consists of several smaller steps, as the gate will need to be extended, loosely installed, and removed to ensure hardware assembly is done effectively.


• 1a. Gate Orientation: Note that either side of the gate can be faced towards the inside or outside of the building. A label on the operating side (side with the center drop pin) indicates the right (RHT) and left (FT) sides of the person facing the operating side.


• 1b. Deciding L-Bracket Placement: As shown in Figure 1, you will need to decide the gate placement and, thus, the L-bracket placement. The L-bracket forms the top hinge of the gate. Stand one gate panel with the bottom gate pin upright against the wall or door frame and mark its placement. Repeat on the opposite side of the opening for the other gate.


• 2. Measuring for & Drilling the Floor Hole: With the gate panel still upright and in line with the L-bracket, have another person help expand the gate. On the floor, mark 11" from the door frame or wall where the gate will be permanently mounted. Then set the gate aside and drill a 3/4" diameter and 3" deep hole in the floor. Place the bearing washer over the hole and then place the bottom gate pin. As shown in Figure 2.


• 3. Bolting the Panels: Bolt the inner and outer panels together at the top, middle, and bottom using carriage bolts, standard washers, and small nuts. As shown in Figure 3. Repeat for all panel connections.


• 4. Attach the Casters & Axle: Attach the casters to the axles with the caster washer and large nut. Then, insert the gate end onto the axle support, secure it with the round head bolt, and tighten. As shown in Figure 4.


• 5. Mounting the Gate: Place the bottom gate pin in the floor hole, extend the gate panels, and hang the L-bracket on the top of the gate panel. Verify where it will be mounted and drill holes into the wall or door frame. *It may be easier to drill the pilot holes if you lift the gate panel out of the floor.
  
• 5a. Securing the L-Bracket: Place the bottom gate pin back into the floor hole. As shown in Figure 5, hang the L bracket on the top of the gate and realign it with the pilot holes. Then secure it to the wall with two 5/16" x 2" lag bolts. Also, consider 3/8" holes and using lead anchors.


• 6. Mounting the Locking Bar: With the gate secured to the door frame or wall, extend the gate and determine the placement of the locking bar on the opposite wall or door frame. Align the padlock holes on the gate and the locking bar, mark and drill for pilot holes, then secure the locking bar to the door frame or wall with 5/15" x 2" lag bolts. As shown in Figure 6.


• 7. Drilling the Center Drop Pin Holes: The center drip pins will help with durability. Expand the gate fully and mark for the center drop pin floor holes. Drill 5/16" diameter and 3" deep holes in the floor, as shown in Figure 7.

Now that your 11-12 foot folding security gate has been installed, you will want to extend and collapse the gate slowly several times to avoid warping and to work out stiffness. Also consider Preferred Security Gates Heavy-Duty Padlock, Cylinder Lock, and Handles.
